While these state-level changes have swept the U.S., a federal decision on legalizing cannabis has not yet been reached. The Alcohol Policy Information System (APIS) explains that in 1970, the Controlled Substances Act made cannabis a Schedule I substance. This categorization means that the potential medical benefits of
cannabis are not considered. Furthermore, it places it in a class of drugs with the highest potential for abuse, along with narcotics like heroin and opium. However, modern research, including a
2014 study published in the Hawai'i Journal of Medicine & Public Health, shows that cannabis may have benefits for both mental and physical health.
